And if so, how to acquire it without jumping through the million hoops on this website: http://dishonoredpc.wix.com/info#!fixer/c60z

Anyone got it?

I'm ready to try it, given that my GAME BREAKING bug has not been solved after 2 years...

Don't know of any such thing and doubt such a thing legitimately exists.

Not sure I'd trust a 'fix all tool' from a website that has no means of discussion and seems to have been thrown together in a few minutes. Looks like snake oil to me.

What is the problem you're having?
